To 6421 wwm z may concern:

Be it known that I, CHARLES L. Dnmnns, a citizen of the United States residing at Claremont, in the county of ullivan and State of New Hampshire, have invented certain new and useful Improvements in Container-Fasteners, of which the followi11 is a full, clear, and exactspecifieatimi.

ly invention relates to container fasteners.

It has for its object to provide an improved container fastener whereb the clo sure oi:- a container may be securely held in place. A further object of iny invention is to provide an improved fastener which is especially adapted to retain its efliectiveness over a long period of use, zindwhich, at the same tiine, may be 1eadilyreleased when desired. Astill urther obj est of my invention is to pi0vide an improved, inexpensive and readily manufactured clamping or locking bail for containers, which is adapted to be readily applied to andt co'perate -With a fastener of standard construction, and to increasethe efiectiveness and life of the fastener to which it is applied. These and other objects and advantages of my immroved construction will, however, herein after more fully appearl In the accompanying drawings, I have shown, for purposes otillustration, several cmbodiments which my invention may assume in practice.

in these drawings,

Figure 1 is a side elevation of a jar equipped ivith my improved fastener, the latter being shown in difierent positionsin full and dotted limes.- A

Fig. 2 is a front elevation of the clamping menfloer shown in Fig, 1.

Fig. is a front elevation of a modified iorm et 'clamping meniber.

Fig. 4 is a partial end elevation of a further 1nodified form ci: clamping member.

In this illustrtivo construction I have shown 1nv invention applied; to a suitable container 1, herein in the shape of a jar, equipped 'with a standard form of baud 2 carrying depending lugs 3 on its opposite sides, and having pivoted in these lugs laterally oxtending ends 4 of a bell crank form of releasing bail 5, with which, in this im-- proved construction, my improved clamp ng or locking bail 6 coperates.

Th1s improved clampmg or lock1ng hall 6 is herein disposable across the closure 7 of the container 1 and adapted to be seated in a usual scat, 8 on the top thereof, herein formed between adjacent inclined surfaces 9. Further, it Wlll be observed that the bail 6 isherein provided with a spring 10 in each of its arms, the same in the construction shown in Fig. 2 each including a single coi], while in the construction shown in Fig. 3 a double coil is used. These spring coils are in turn herein also connected witli the releasing bail throgh lever-like coperating spring locking arms 11 of suitable form, the same herein ;Eorming extensions from the outer sides et the coils and having their lower. ends seated in sockets or eyes 12 formcd by bending the releasing bail 5 to form the arms ion that bail. These arms 11 nuay be disposed with respect to the spring coils in various relations and assume various forme. As shown they are disposed vertically relative to the body of the bail 6 and in substantial parallelism with the spring eoils, and are in the form of bell cranks, the same, in the form shown in Figs. 1 and 2, extending laterally and clown *.vardly :trom the springs and then being bent remrsely laterally and clownwardly; while in the form shown in Figs. 3 and 4, they are bent more directly laterally and then more directly clownwardly.* Each of these arms is herein also provided with an inwardly extended end 13 received in :1 socket or eye '12, in such a manner as to enable movement of the releasing bail to move the arms 11 and thereb clamp or release the bail 6 at will.

In considering the clamping operation of my improved construction, let us assume that the parts are in the released or dotted lino position shown in Fig. 1, with the bail 5 raised and recly movablelahout its Pivot in the luge 3. In this position, it Will be observod that the imper onde of the arms 11 are above the pivots 01. the' releasing bail, that the lowenencls of the arme 11 are raised, and that the 'springs 10 are drawn laterally to the left so that the bail 6 may be readily moved backward to the left about its pivot in the eyes 12, thus permitting free removal of the cover 7. When, hOW- everi the bail 5 is depressed, it Will be ob served that as its arms4l move about their pivots in the lugs 2, the lower ends of the hell crank arms 11 on the bail 6 are swung downward and to the right to points on the 7 'position of the partsin the locking position thus assumed being sueh that the pivots of the arms 11 in the eyes 12 are also substantially direotly boneath the spring coils and 7 in substantial parallelism with said portion the r13ointsof.contact of the upper part of the then tensioned bail npon the sh0niders of the cover 7, a very' powerful clamping action thns being produced, Vhen it is desired t0 release the Closre, however, it will be observed that all,that it is necessary to do is to swing np the releasing bail 5 to cause the parts again to assume the po sition shown in dotted lines in Fig. 1.

As a,result of my improved construction includingthe spring eonnected arms, itwil]. be observedthat the bail 6 is caused to press upon the top 7, with a very considerflale force oapable of maintaining an effective herrhetio sea1 whenever d sired. the provision of the coperating prings 10 and ,11, the desired elasticityof the bai]. 6 is also n1a1ntamed to such an extent tha t,

while n ordinary straight bail aftenbnt short us willbecome. atigned'and useless without, rebending,.my improved bail be used and re-used almost 1ndehmteiy w1thoutrany attention whatsoever. Attentien is also directed tothe fact that, When ininoperative position, my improved bail may et'be readily removed whenever de sired by simply pressing one of itsends 13 out of the eyes 12, thereby enabling it to be removed from a broken jar or bottle and placednpon another when dcsired;

VVh1le 'I have in tlns apphcat1on spemfica11y described several embodiments of my invention, it Wili of course be nnderstood that the same may be mod1fied andembod1ed in other -forms, as for instance through the use of modified forms of lever connections or sarin s without de 3aitin 'froin the *ativey vrtically disposed bel1' rank portion and a ooperating spring'coil, said coi1 Through spirit of my invention or from the seope being disposed in substantial parallelism with said portion and between the upper arm'thereof and the body of the bail.

'2. A Closnre clamping member comprising a bail having on eachend thereof a relativeiy verticaliy disposed be1l orank portion and a coperating spring coil disposed and between the upper arm thereof'and the body of thebail, said portion forming an extension of the onter side or each coil.

In a container closnre, a container, a ciosure, a releasing bail pivoted onthefor-- mer, and a clamping bail havi1ig;in each side portion thereof a ,spring coil and a beii crank disposed in substantial paralieiism, the lower end ofthe latter being pivotaily connected to said releasing bail at a point adjacent the pivot thereof and movablelateraly with said bail to G1flmping and releasingpbsitions on opposite Sidesof the pivot theieof. fi V 7 r 4. In a Container closnre, a container, a closnre, a releasi1igbailpivoted onsaid container, and a Clamping bail having in each side portion thereof a spring.coil and a bei1 'Crank disposed in snbst antial parallelisnrl'therewith' and forming an extension threof, the upper end of said be1l orank beiiig disposed above the pivot ofsaid re leasing bail andconnected to said spring c0il and the lower end being piVotally Conhected tdsaid i eleasingbaii at a point adjacent itsfpivot. J

5. In cornbination, acontainer,a clOsnre, a reieasing bail liaving lateraliy extending portions pivotd on said container at their ends and presenting eyes at their* junction with the releasing bail, and a lamping ai1 disposed over said ciOsnie having a spriheoil in each'side therof and a.bell crank lying in substantialpztra1llism with said coil and formihg an.extensionthereflt, eah of said bell cranks having its upper end disposed above thepivot of said rleasing bail and connected ,to said spring coil Intestimony whereof ax my signature.
